我在使用ndk-build的时候总是报这个错，奇怪的指向opencv库代码。
这是我收到的错误信息:
./obj//armeabi/objs/QRCA/QRCA.o: In function `~SURF`:
/----Path---/../sdk/native/jni/include/opencv2/nonfree/features2d.hpp:107: undefined reference to `vtable for cv::SURF`

~/Downloads/android-ndk-r8b/sources/cxx-stl/gnu-libstdc++/4.6/include/bits/stl_vector.h:780: undefined reference to `VTT for cv::SURF`
这是我的 Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include ../sdk/native/jni/OpenCV.mk
LOCAL_MODULE := QRCA
LOCAL_SRC_FILES := QRCA.cpp
LOCAL_C_INCLUDES += $(LOCAL_PATH)
LOCAL_LDLIBS += -llog -ldl
LOCAL_WHOLE_STATIC_LIBRARIES := gnustl_static
include $(BUILD_SHARED_LIBRARY)
非常感谢任何建议!
最佳答案
关于android - 使用 NDK 构建时在 OpenCV/nonfree/features2d 中未定义，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12871137/
